Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door and window reinforcing lining structure that blocks thermal bridging. Background Technology

[0002] As people's awareness of energy conservation continues to rise, the requirements for the energy efficiency of doors and windows are also increasing. Traditional door and window profiles use steel reinforcement inside to strengthen the structure. While steel reinforcement does provide some reinforcement, its high heat transfer and conductivity coefficients significantly compromise energy efficiency. This is especially true in passive doors and windows where steel reinforcement is used as the inner lining, making it difficult to meet the requirements of passive windows and resulting in unsatisfactory energy-saving effects.

[0003] A search revealed Chinese publication number CN210798667U, which discloses a door and window reinforcing lining structure for blocking thermal bridging, solving the problem of poor energy efficiency in existing door and window reinforcing linings. This utility model includes an upper component and a lower component housed within a profile. Both components comprise a PVC outer shell, a steel lining, and polyurethane filler. The PVC outer shell fits into the profile, the polyurethane filler is disposed inside the PVC outer shell, and the steel lining fits into the PVC outer shell. This utility model enhances corner connection strength, prevents excessive deformation of the sash, improves the performance of doors and windows, effectively blocks thermal bridging, and improves both the energy efficiency and strength requirements of doors and windows. It achieves energy-saving effects through a cleverly designed energy-saving structure without compromising the basic strength performance requirements of doors and windows.

[0004] The aforementioned patent mentions in its beneficial effects that "the use of a PVC outer shell and polyurethane filler to replace the traditional steel lining structure effectively reduces the heat transfer coefficient and has a good energy-saving effect." However, in the existing technology, the connection between some components is often not tight enough and lacks effective sealing measures. Furthermore, the traditional door and window structure lacks effective positioning and constraint mechanisms during installation, which can easily lead to assembly misalignment. Therefore, a door and window reinforced inner lining structure that blocks thermal bridges is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a door and window reinforcing lining structure that blocks thermal bridging, aiming to improve the problem that the connection between some components in the prior art is not tight enough and that installation misalignment is easy to occur.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A door and window reinforcing lining structure for blocking thermal bridges includes a lower component and an upper component. The lower component and the upper component are both fixedly connected with a sealing mechanism, and the lower component and the upper component are both provided with a heat insulation mechanism.

[0008] The installation sealing mechanism includes a first locking interface, which is externally fixedly connected to the top of the lower component. A second locking interface is fixedly connected to the bottom of the upper component. A first locking block is fixedly connected to the side of the lower component near the second locking interface, and a second locking block is fixedly connected to the side of the upper component near the first locking interface. Sealing strips are fixedly connected to the opposite sides of both the first and second locking blocks. A protruding rod is fixedly connected to the top inner wall of both the lower and upper components. Multiple positioning balls are rotatably connected to the bottom of the protruding rod. A guide rod is fixedly connected to the bottom inner wall of both the lower and upper components.

[0009] Furthermore, the lower and upper components form the main framework, and the sealing mechanism ensures a stable connection between the lower and upper components through a snap-fit ​​method, thus creating a robust framework. The sealing strip improves the sealing performance and prevents air and moisture penetration, the positioning ball bearings reduce assembly misalignment, and the guide rods assist in accurate alignment of the components, all of which together enhance the structural performance.

[0010] As a further description of the above technical solution:

[0011] The heat insulation mechanism includes a mounting shell, and both the lower component and the upper component are provided with deformation absorption layers inside. The outside of the mounting shell is fixedly connected to the inside of the deformation absorption layer, and an inner liner is fixedly connected to the inner wall of the mounting shell. A heat insulation layer is filled between the mounting shell and the inner liner.

[0012] Furthermore, the installation shell blocks external heat conduction, the deformation absorption layer buffers temperature difference stress to increase structural durability, the inner lining frame transmits stress to enhance structural strength, and the insulation layer blocks air convection and reduces heat radiation, effectively blocking thermal bridges, reducing indoor energy consumption, and maintaining a comfortable indoor temperature.

[0013] As a further description of the above technical solution:

[0014] The outer side of the second card connector engages with the inner side of the first card interface, and the outer side of the first card connector engages with the inner side of the second card interface.

[0015] Furthermore, the interlocking mechanism between the second interlocking block and the first interlocking interface, and between the first interlocking block and the second interlocking interface, connects the lower and upper components in a simple and efficient manner, ensuring the stability of the structure. This helps maintain the overall structural stability of the door and window lining components and prevents problems such as loose components from affecting the normal use of the doors and windows.

[0016] As a further description of the above technical solution:

[0017] The bottom end of the lower component is fixedly connected with multiple support legs. The adjacent side of the first card interface and the second card interface is in contact with the distant side of the two sealing strips. The sealing strips are made of EPDM rubber.

[0018] Furthermore, the multiple supports at the bottom of the lower component further distribute the structural load, improving the overall structural stability during installation, ensuring the stability of the doors and windows during use, and reducing safety hazards and performance degradation. The sealing strip is made of EPDM rubber, which expands to fill microscopic gaps during snap-fitting, greatly improving the sealing performance of the structure, effectively preventing the penetration of air and moisture, helping to maintain a stable indoor environment and reduce energy loss.

[0019] As a further description of the above technical solution:

[0020] The top of the mounting shell is provided with a circular groove, and the outer wall of the positioning ball engages with the inner wall of the circular groove. The positioning ball is made of stainless steel.

[0021] Furthermore, the engagement of the stainless steel positioning balls with the circular groove at the top of the mounting housing, along with the connection of the protruding rod, enables radial self-adaptive alignment of the mounting housing, reducing assembly misalignment. This helps improve assembly accuracy and efficiency, ensures proper connection between components, and thus enhances the performance and stability of the entire structure.

[0022] As a further description of the above technical solution:

[0023] A positioning protrusion is fixedly connected to the bottom end of the mounting shell, and the inner wall of the positioning protrusion is slidably connected to the outer wall of the guide rod.

[0024] Furthermore, the sliding connection between the positioning cam and the guide rod provides axial constraint, ensuring accurate alignment of each component during installation and contributing to the stable installation of the entire structure.

[0026] The mounting shell is made of PVC, the inner liner is made of glass fiber reinforced nylon, and the inner liner is X-shaped.

[0027] Furthermore, the PVC mounting shell has low thermal conductivity, which can block heat conduction from the external metal frame. The X-shaped inner liner made of glass fiber reinforced nylon can improve bending stiffness, evenly transfer stress to the insulation layer, enhance the overall strength of the structure, and ensure the stability of the structure under different stress environments.

[0028] As a further description of the above technical solution:

[0029] The heat insulation layer is made of polyurethane foam, and the deformation absorption layer is made of silicone rubber.

[0030] Furthermore, the polyurethane foam insulation layer fills the cavity with a closed-cell structure. The closed-cell structure blocks air convection and reduces heat radiation efficiency, greatly improving the thermal insulation performance of the structure. The silicone rubber deformation absorption layer buffers the material expansion and contraction stress caused by temperature difference through elastic deformation, avoiding damage such as cracks caused by temperature changes and increasing the durability of the structure.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the first and second snap-fit ​​interfaces are snap-fitted with the first and second snap-fit ​​blocks to connect the lower and upper components. During snap-fitting, the sealing strip is compressed and expands radially, filling the microscopic gap between the snap-fit ​​block and the interface, effectively preventing the penetration of air and water vapor, ensuring the airtightness of the door and window structure, helping to maintain the stability of the indoor environment, and reducing energy loss due to air exchange. During installation, the sliding fit between the guide rod and the positioning convex plate provides axial constraint, and the positioning ball at the bottom of the convex rod rolls into contact with the top circular groove of the mounting shell to achieve radial adaptive alignment, reducing assembly offset, so that the entire door and window reinforced inner lining structure can maintain a stable structural state during installation and use.

[0033] 2. In this utility model, the mounting shell is made of PVC material, which serves as the heat insulation substrate to block external heat conduction. The X-shaped glass fiber reinforced nylon inner lining frame improves the bending stiffness and transfers stress to the polyurethane foam heat insulation layer. The closed-cell structure of the heat insulation layer blocks air convection and reduces heat radiation efficiency. At the same time, the silicone rubber deformation absorption layer buffers the stress caused by temperature difference. Through the combination of the above structures, the structure not only has good heat insulation performance, but also maintains structural stability under different temperature environments, thus extending its service life.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a door and window reinforcing lining structure that blocks thermal bridging, comprising a lower component 1 and an upper component 2. Both the lower component 1 and the upper component 2 are internally fixedly connected to a sealing mechanism 3, and both are internally equipped with a heat insulation mechanism 4. Multiple supports 5 are fixedly connected to the bottom end of the lower component 1. The lower component 1 and the upper component 2 form the main body of the entire door and window reinforcing lining structure. The lower component 1, as the bottom structure, provides basic support for the entire structure, and its multiple supports 5 further distribute the structural load and improve installation stability. The upper component 2 cooperates with the lower component 1, and the two are quickly connected through the sealing mechanism 3.

[0042] Specifically, the lower component 1 and the upper component 2 form the basic framework of the entire door and window reinforced inner lining structure. The lower component 1 further distributes the structural load through multiple support legs 5 at the bottom, which improves the installation stability of the overall structure, ensures the stability of the door and window during use, and reduces the safety hazards and performance degradation that may be caused by structural instability.

[0043] The sealing mechanism 3 includes a snap-fit ​​interface 301, which is externally fixedly connected to the top of the lower component 1. A snap-fit ​​interface 302 is fixedly connected to the bottom of the upper component 2. A snap-fit ​​block 304 is fixedly connected to the side of the lower component 1 near the snap-fit ​​interface 302, with the exterior of the snap-fit ​​block 304 engaging with the interior of the snap-fit ​​interface 302. A snap-fit ​​block 303 is fixedly connected to the side of the upper component 2 near the snap-fit ​​interface 301, with the exterior of the snap-fit ​​block 303 engaging with the interior of the snap-fit ​​interface 301. Snap-fit ​​interfaces 301 and 302 provide connection interfaces for snap-fit ​​blocks 303 and 304, respectively. This snap-fit ​​method connects the lower component 1 and the upper component 2 simply and efficiently, ensuring the stability of the structure. Sealing strips 305 are fixedly connected to the far sides of snap-fit ​​blocks 303 and 304. The near sides of snap-fit ​​interfaces 301 and 302 are in contact with the far sides of the two sealing strips 305. The sealing strips 305 are made of EPDM rubber. During snap-fit, the sealing strips 305 expand radially under pressure, filling the microscopic gap between the snap-fit ​​blocks and interfaces, increasing sealing performance, and preventing the penetration of air and moisture. This plays an important role in improving the sealing performance of the structure. A protruding rod 306 is fixedly connected to the top inner wall of both the lower component 1 and the upper component 2. Multiple positioning balls 307 are rotatably connected to the bottom of the protruding rod 306. A circular groove is opened at the top of the mounting shell 401, and the outer wall of the positioning balls 307 engages with the inner wall of the circular groove. The positioning balls 307 are made of stainless steel to improve wear resistance. The protruding rod 306 is connected to the lower component 1 and the upper component 2. The positioning ball 307 makes rolling contact with the top circular groove of the mounting shell 401, so as to realize the radial adaptive alignment of the mounting shell 401 and reduce assembly offset.

[0044] Specifically, the installation sealing mechanism 3 achieves rapid connection between the lower component 1 and the upper component 2 through the cooperation of the snap-fit ​​interface and the snap-fit ​​block, and ensures structural stability. At the same time, the sealing strips 305 on both sides of the snap-fit ​​block expand and fill the micro gaps during snap-fit, which greatly improves the sealing performance of the structure, effectively prevents the penetration of air and water vapor, helps maintain the stability of the indoor environment, and reduces energy loss.

[0045] Reference Figure 1 , Figure 3 and Figure 4The thermal insulation mechanism 4 includes a mounting shell 401, which serves as the thermal insulation substrate. Its low thermal conductivity blocks heat conduction from the external metal frame, acting as the first line of defense against heat transfer and effectively reducing heat transfer to the interior of the structure. The mounting shell 401 is made of PVC. Both the lower component 1 and the upper component 2 have a deformation absorption layer 404 made of silicone rubber. The mounting shell 401 is externally fixed to the interior of the deformation absorption layer 404. The silicone rubber deformation absorption layer 404 covers the periphery of the mounting shell 401, buffering the material expansion and contraction stress caused by temperature differences through elastic deformation, preventing structural damage such as cracks due to temperature changes, and increasing the durability of the structure. An inner liner 402 is fixedly connected to the inner wall of the mounting shell 401. The inner liner 402 is made of glass fiber reinforced nylon and is X-shaped. A heat insulation layer 403 is filled between the mounting shell 401 and the inner liner 402. The heat insulation layer 403 is made of polyurethane foam. The biomimetic mesh structure of the inner liner 402 improves the bending stiffness and can evenly transfer stress to the heat insulation layer 403, thereby enhancing the overall strength of the structure and ensuring the stability of the structure under different stress environments. At the same time, the polyurethane foam heat insulation layer 403 fills the cavity with a closed-cell structure. The closed-cell structure blocks air convection and reduces heat radiation efficiency, which is a key part of the heat insulation and greatly improves the heat insulation performance of the structure. The bottom of the mounting shell 401 is fixedly connected to a positioning protrusion 405. The bottom inner walls of the lower component 1 and the upper component 2 are both fixedly connected to guide rods 308. The inner wall of the positioning protrusion 405 is slidably connected to the outer wall of the guide rod 308. The guide rod 308 and the positioning protrusion 405 are slidably engaged to provide axial constraint, ensure accurate alignment of each component during installation, and contribute to the stable installation of the entire structure.

[0046] Specifically, the components in the insulation mechanism 4 work together to improve the insulation performance of the structure in multiple ways. The mounting shell 401 blocks external heat conduction, the inner lining frame 402 transmits stress to enhance structural strength, the insulation layer 403 blocks air convection and reduces heat radiation, and the deformation absorption layer 404 buffers temperature difference stress to increase structural durability. Overall, it effectively blocks thermal bridges, reduces indoor energy consumption, and maintains a comfortable indoor temperature.

[0047] Working principle: The quick connection between the lower component 1 and the upper component 2 is achieved by using the snap-fit ​​of snap-fit ​​block 2 303 and snap-fit ​​interface 1 301, and snap-fit ​​block 1 304 and snap-fit ​​interface 2 302. A sealing strip 305 is provided between them. The sealing strip 305 is made of EPDM rubber. During the snap-fit ​​process, it is compressed and expands radially, which simultaneously fills the micro gap between the snap-fit ​​block and the interface, increasing the sealing performance. During the installation process, the sliding fit between the guide rod 308 and the positioning convex plate 405 provides axial constraint. At the same time, the stainless steel positioning ball 307 at the bottom of the convex rod 306 forms rolling contact with the circular groove at the top of the mounting shell 401, realizing the radial self-adaptive alignment of the mounting shell 401 and eliminating the assembly offset caused by machining tolerances. Meanwhile, the support leg 5 serves as the bottom support point, further dispersing the structural load and improving the installation stability.

[0048] The PVC mounting shell 401 serves as the thermal insulation substrate. Its low thermal conductivity blocks the heat conduction of the external metal frame. The X-shaped glass fiber reinforced nylon inner liner 402 is embedded inside the mounting shell 401. Through its biomimetic mesh structure, it enhances the bending stiffness and evenly transmits stress to the thermal insulation layer 403. The polyurethane foam thermal insulation layer 403 fills the cavity with a closed-cell structure, blocking air convection and reducing heat radiation efficiency. The silicone rubber deformation absorption layer 404 covers the periphery of the mounting shell 401. Through elastic deformation, it buffers the material expansion and contraction stress caused by temperature differences, thereby increasing the overall thermal insulation performance and strength of the profile.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
